ing is a specification.

This invention relates. to ringspinning frames, and has for itsprincipal object to provide an improved means whereby a much maybe'wound on the cop or 'quil for use in feeler-looms where the loom isstopped or an empty quill thrown out and a new quill inserted by theaction of a feeler-finger which bears against the quill.

In looms of this class it is desirable to retain sufficient thread onthe quill or cop to make one or two shots after the fecler has moved tooperative position in order to avoid a thin place in the cloth. To accomplish this, a so-called bunch" is Wound on the cop or quill at thebeginning of the winding operation, the bunch being usually arrangednear the base of the cop at apoint beyond the lane of movement of thefeeler-linger, this unch containing several yards of thread, so that twoor more shots may be-made after thefeeler assumes operative position;

The principal ob ect of the invention is to so arrange and construct aring-spinning frame that the bunch may be readily'formed at the properpoint, and after a sulhcient quantity of thread has, been wound to formthe bunch the traverse mechanism is automatically adjusted to permit-theordinary winding.

A furtheriobject of the invention is to provide an attachment which maybe applied to existing spinning-frames for this purpose.

A still further ObJGCl/Of the invention is to provide for theiMiJLlSill'IlBIlt of the traverse mechanism,so thatthering-rail may belowered to the proper positlon to form a bunch.

\Vith these and other objects in view, as will more fully hereinafterappear, the invention consists in certain novel features of constructionand arrangement of parts hcrein after fully described, illustrated inthe ac coinpanymg drawings, and particularly pointed out in the appendedclaimsfiit being understood that various changes in the form,

proportions, size, and minor details of the structure may be madewithout departing.-

from the spirit or sacrificing; any of the advantages ol'the invention.

,In the accon'ipanying drawings, Figure 1 is an elevation, partly insection, of a portion of a spinning-frame arranged and constructed 'inaccordance-With the invention. Fig. a detail perspective view of thelm-ver portion of the mechanism, showing particularly the constructionand mounting of the builderarm and the means for automatically shiftingthe builder-arm roller from engagement with the buncher-eam intoengagement with the builder-cam. Fig. 3 is a sectional elevation of themechanism for taking up the slack and traversechain to adjust thering-rail to the lowest position for the formation of the bunch. Fig. 4is a plan View of the mechanism shown in Fig. 3.

- Similar numerals of reference are employed to indicate correspondingparts throughout the several figures of the drawings.

In the, drawings, A represents the end frame, and B thespindleaail, ofan ordinary form of spinning-frame The ring-rail C is operated in theusual manner through lifterrods D and the traverse mechanism, whichincludes the usual chain E, the lower endof the chainbeing connectedto abuilder-arm 10, that is fulcrumed'on a stud i 1, carried by the frame.

In the frame of the machine is supported a cam-shaft 12, carrying abuilder-cam 15 of the ordinary construction, this cam serving to depressthe buildenarm 10 for the purpose I of operating the traverse mechanism.In the present instance the builder-cam carries a bunchcr-cam 16, whichin the present instance is in the form of a disk, the pcripliicry ofwhich is divided into a plurality of cams 16, each designed to impartslight vertical movei'nent to the builder-arm it) for the purpose ofmoving" the ring' rail in a vertical path during the winding of thebunch, the lift oi each cam being such thatthe .ringerail travcrses fromtop to bottom of the bunch at each movement, and the bunch. istl'iercfore formed of crossed threads, which present a relatively hardsurface on which the main winding may take place without danger of theyarn being pressed between or caught by the yarn forming the bunch, thusavoiding the breakage of the yarn, which frequently occurs where thehunch is formed of simple nncrosscd turns. i

The buildcuarm 10 is provided with a transverselydisposed openingcarrying a .stud 17,011 the outer end of which is mounted anantifriction-roller' 18, which is arranged to be operated u on by thelauncher-cam 16 until the bunch is formed and then is automaticallyshifted to be operated upon by the 'builder-cam 15 during the fhrther'and ordinary winding of the cop or quill. In order to facilitate thetransfer of the roller 18 from one cam to the other, it will be notedthat the deepest indentations between the projecmove the lever in suchmanneras to force the roller 18 from engagement with the bunchercam intoengagement with the builder-cam. This movement, however, is resisted orprevented by a lo'cking mechanism which holds the lever 19 until thebunch has been wound and then releases it, allowing the spring to actand the roller to move into engagement with the builder-cam to completethe regular winding of the cop orquill.

At the outer end of the builder-arm is ar ranged the usual mechanism forgradually taking up the traverse-chain in building the cop; but thismechanism requires for its operation the full stroke of the builder-arm,and the limited stroke imparted by the bunchercam is not sufiicient tobring it into play, so that the traverse-chain is not taken u untilafter the bunch is formed and the ro ler 18 passes under the control ofthe builder-cam 'liigidly secured to the hub or collar of thebuilder-arm is a locking-bar 22, carrying one or more guides 23 for thereception of a longitudinally-movable bar 24, the outer end of which ispivotally connected to the lever 19. l The inner end of the bar 24 hasan outwardly-- extended arm 26, and from the inner face of 7 this armextend yoke-like guides 27, in which a vertically-movable rack 28 ismounted, the position of theirack at the starting of opcrations beingdetermined by a pin 30, which may be placed in an one of a number ofopenings 31, that are ormed in the rack, the pin then resting on topof-the upper guide 27. The rear face of the rack-bar is provided withsmall teeth 'or serrations 33, that engage against the pointed end ofthe bar 22, and as the rack-bar is moved upward step by step thesuccessive serrations are entered by the point of the bar and therackbar is held in the position to which it is elevated. The rack-bar isoperated by a pawl 34, that is hung at one end of a lever 35, pivoted ona bracket 36 and hearing at its opposite end a Ward movement of thepawl. The pawl-carrying end of the lever 35, together with the pawl, isheavier than the opposite end, so that the pawl and'this end ofthe leverwill move down by gravity. In this manner the rapid ity with which therack-bar is moved tore lease" position may be accurately adjusted, andby thus adjust' the length of time which the roller 18 iS ll fiOWed toremain in engagement with the buncher-cam the quantity of yarn wound toform a bunch may be adjusted. Further adjustment may also beaccomplished by altering the osition of the pin 30 so that the rack wille raised to a greater or less distance before released.

The bar 24 is provided with guides 40 for the reception of a slidablebar 41, the outer end of which is pivoted to a hand-operated lever 42,that is pivoted on a bracket 43, projectin from lever 19'. Thehand-lever is force outward from the lever 19 by means of a. smallcompression-spring 44. At the inner end of the bar41 is a plate 45,thatis arranged to engage with the pawl 34 in order to prevent thelatter from remaining in contact with teeth of the rack b'ar while theparts are be.- ing ad'usted to" osition for the formation of a freshunch. n the o eraticn of this .portion of the mechanism tile pawl'34isreeiprd, eated until the end of the-rack-bztr is above the bar22,whereupon the spring 21 acts to pullout the bar 24and bar .41, togetherwith the rack-bar, and the latter will move away from the pawl, whilethe opposite end of lever 19 moves in the direction of the builder-armand carries the stem 17 over until the roller 18 moves into contact withthe builder-cam 15. In effecting readjustment of the parts the operatorgrasps the handled lever 42 and the end of the lever 19, and b pressingthem together the bar 41 is forced inward until plate 45 holds theengaging end of the pawl well out of contact with the teeth of therack-bar, so that said rack-bar when pushed be ond the pointed end ofthe bar 22 ma -fal by gravity to its lowest position in rea iness foranother operation .In order to place the bunch in proper osition on thecop or quill, it is necessary t at the machine. This slidhble frame 51is con nccted to a fixed eve 54 on the bracket by means of a helicaltension-spring 55, that tends normally to pull the left, and thus movethe traverse -chain and rocker-arms and depress the lifter-rods D.

This movement, however, is resisted by the counterweights. of thelifter-rods, and the spring 55 is not strong enough to overcome theresistance thus cfl ereih'so'thnt the tlnV- erse-cha-in is held understress and is moved, as usual, in one direction by the builder-arm andin the other direction" by the counterwei hts of the lifter-rods, v

' he bracket 53 is provided with a slot 57, in

which spivot-pin58 may be locked, and on the pivot-pin is mounted a hook59-, that is hold upward by a spring 60,.sz1id-hook serving to engagewith the frune 51 and lock thc ssm e in the position shown inFig. 3 incase said frame 51 is moved to the left. To RCCOlll-r plish this, therockerdrsme of the first lifter rod is provided with a pedal 60, which.may

be depressed by the operator, thus removing the influence of thecounterweight from the traverse -chain, and as soon as'this is done thespring-"55 draws the frame 51-to the left, and the hook-5S) immediatelyengages and locks said frame in its adjusted. position, after whichthehook may be removed and the counterweight again will be allowed toact.

The edjustinentof'the roller 50 takes up a portion of the traverse-chainand pulls down the ring-rail to the proper point for the forma- -tion ofthe bunch, and as the small bunchercams 16 move over the roller'l 8 thebuilderarm will be oscillated through it short arc,

and the movement will be transmitted through the trsverse-chein totheringmsil during the for 'mation of the bunch.

The hook 09 is provided with an opening for the passage of avertically-movable rod the frame is locked bythe hook 59 thedownweirdressure of the pedalis-relieved, and the ot er parts beingedjustedfwith the'roller 18in alinement with thebuncher-csmthe op-"citation proceeds. end lowered very slightly, but to an extent Thebuilder-arm is raised sufiicient to traverse the ring-rail the fullheight of the bench at eechoperetion, so that the tread iscro'ssediand arelatively hard bunch is formed'on which the subse' ucnt winding mayproceed'wi-thout danger o the operation -progre'sses each til ne thebuildererm is moved down the iuilder-eani' will'nlso frame 51 to the,

buildeiwirm to engage the roller 37 and rock the lever 35, this movementbeing transmitted through the pawl 34 and the rack-bar being raised oneor more teeth, in accordance with the distance throughm'liich the lever35 moves. As soon 7c as the lower end of the pawl-bar is level with Ithe top of the bar 22 the spring 21 acts to pull the ber24 and therack-'baroutward,
